TL;DR: In this article, the effects of fabrication spreads and noise in a series array of DC bi-SQUIDs were investigated through numerical simulations of phase equations derived from circuit diagrams, and it was shown that the effects to the voltage response of arrays of identical bi-sQUIDs can be drastic.

TL;DR: In this article, a study of the dependence of current gain on the SFIFS injector and SIS acceptor barrier transparency is presented, and it is shown that making the acceptor junction much more transparent than the injector junction results in improvement of the current gain; in particular it can exceed unity.
